Questions about be quiet! Silent Wings 4 Pro PWM fan

The warranty period has been adjusted. :)

The Silent Wings 4 Pro PWM fan (120 mm) from be quiet and the Noctua NF-A12x25 PWM fans have several key differences and similarities: ## Noise Level - The Silent Wings 4 Pro PWM fan has a maximum noise level of 36.9 dB(A) at 100% PWM/12V, which is relatively quiet but can be louder at its highest speed settings. - The Noctua NF-A12x25 PWM fans are generally quieter, especially at lower speeds, and maintain a lower noise level even when normalized to the same volume as other fans. ## Air Pressure and Performance - The Silent Wings 4 Pro PWM fan is designed to deliver high air pressure, with a static pressure of 5.31 mm H2O, which is beneficial for cooling demanding hardware and radiators. - The Noctua NF-A12x25 PWM fans also provide strong air pressure but are optimized more for quiet operation and balanced performance. They excel in tests normalized to a specific noise level, often outperforming other fans in such conditions. ## Speed and Versatility - The Silent Wings 4 Pro PWM fan has a maximum speed of 3000 RPM and features a speed switch that allows users to adjust the maximum RPM to 1600, 2500, or 3000 RPM, providing flexibility for different cooling needs. - The Noctua NF-A12x25 PWM fans typically operate at lower maximum speeds but are highly efficient and quiet across their operational range. ## Overall Comparison - In terms of maximum performance, the Silent Wings 4 Pro PWM fans often take the lead due to their high maximum speed, but they become louder in these conditions. The Noctua NF-A12x25 PWM fans are quieter and offer excellent performance when noise is a critical factor. In summary, while both fans are high-quality options, the Silent Wings 4 Pro PWM fan excels in high-performance scenarios and offers more versatility in speed settings, but at the cost of slightly higher noise levels at maximum speeds. The Noctua NF-A12x25 PWM fans are quieter and more balanced, making them ideal for users prioritizing silent operation.

Unfortunately, we also don't know why bequiet! doesn't yet offer the colour white. However, we hope that this will soon be the case.

you can forget that...it only runs corsair fans

At the end of the specifications there is the function [Report wrong data]. This should do more than "a question about the product".
